Abstract We propose XMM-Newton observations of new candidate supersoft X-ray sources,SSSs, in the Magellanic Clouds, MCs, in order to confirm and study theirnature. The 20 ks exposures will allow to determine a precise position,spectral and temporal investigations. Finding new SSS in the MCs is crucialfor X-ray source population studies and will provide new information on thephysics of individual objects and on the class of SSSs as such. In particularwe will address the question if persistent low-luminosity SSSs exist, whichis not easily to understand in the framework of stable burning at highaccretion rates, or if they are highly variable.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
